Call UpdateWindow() after scrolling or moving/resizing the window. This

2002-11-07  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkgeometry-win32.c (gdk_window_copy_area_scroll,
	_gdk_window_move_resize_child): Call UpdateWindow() after
	scrolling or moving/resizing the window. This causes a WM_PAINT
	message to be sent to the window procedure. Improves scrolling a
	lot, for instance in testgtk's "scrolled windows" dialog or
	gtk-demo's "Text Widget".

	Without calling UpdateWindow(), Windows generates a WM_PAINT only
	when there is no other message in the queue. Thus, while you keep
	moving the scrollbar slider and generating mouse messages, no
	WM_PAINT messages are sent.
